I have used super nice quilters cotton to fat quarters from walmart and have had wonderful results. My next one will be from light weight denim. I just ordered my magnetic closures from Lees Crafts and Things and got 25 for $23.23 total way cheaper than I found anywhere else. I would figure your total batting needs for the fusible pellon and use a coupon as I paid nearly $8 per yard at Hobby Lobby. Use heavy weight interfacing for pockets if you are on a tight budget and they still come out very nice. I have had a lot of fun making mine.
